A memorial is a special place or thing that we create to remember someone who has died. Imagine if you had a special toy that you loved very much, but one day it broke and you couldn't play with it anymore. You might feel sad and want to do something to remember how much you loved that toy. That's what a memorial is like, but instead of a toy, we remember someone who was very important to us. We might put up a picture of them or make a special garden with their favorite flowers. We visit the memorial to remember them and think about all the good times we had with them. It helps us feel better and keep their memory alive in our hearts.
